Patented July 10, 1906.

Application filed December 21,1904. Serial-N0. 287,835.

To all whom it may concern:

Be it known that I, ADoLPH ROSENBERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Window-Fasteners, of which the following is a s ecification.

My invention re ates particularly to window-fastening devices by means of which the window maybe secured either in a wholly closed or partially closed condition, the extent of opening being controllable within the limits for which rovision is made.

My primary o bject s to provide a simple and inexpensive fastening of improved construction and operation which will serve so to secure a window as to prevent the entrance of unauthorized arties, while permitting the window to be kept partially open for ventilation purposes. I

The invention is illustrated in the accompanying drawings, in which Figure 1 represents a broken inner perspective view of a Window equipped with my improvedifastener; Fig. 2, a broken vertical section taken as indicated at line 2 of Fig. 1', but showing the window in the closed condition; Fig. 3, a rear view of the fastening, the full lines showing the bolt in engagement with the retainer as in the closed condition of the window; Fig. 4, a perspective view of the locking-bolt and its casing; Fig. 5, a view of a key employed in connection with the bolt; Fig. 6, a view of the bolt partl in section; and Fig. 7, a section nhowing the lrey in engagement with the bolt,; the section being taken as indicated at line 7 ofFig. 6.

In the preferred embodiment shown, A represents the up er sash of the window; B, the lower sash; C a vertically disposed fastener member, keeper, or retainer attached to the up er sash, and D a horizontally-disposed bo t-equipped fastener member attached to the lower sash.

The member C is an elongated member which may be a stamping or a casting, said member being dished or struck up so that it is provided with side flanges c and a raised wall 0, having cut therein a longitudinal slot 0 terminating at its lower end in an enlargement 0 At its upper end the member has an inclined wall a, meeting the raised wall c and whose sloping outer surface serves to lift or retract the bolt when the window is being changed from its wide-open condition to its closed condition. At the enlarged opening 0 is provided an inclined tongue or member 0 upon whose outer sloping surface the bolt may ride in entering or leaving the slot 0 ,At the extreme lower end of the member 0 is a socket 0, provided by forming an opening 0 in the raised wall 0, the metal being'struck in at the upper margin of said opening to afford a lockingshoulder a and the lateral margins of said opening affording flanges c". The construction described .afiords flanges 0 flankin the slot 0 and the side flanges c are curved to afiord a series of internal cavities 0 which enable the sashes to be securely fastened together at any desired relative position when the bolt is entered in the slot 0 The member 0 is provided with screw-receiving perforations e for attachment to the sash, and the flanges c are struck in at points 0 as shown.

The member D comprises a casing d, having a horizontal bore and rovided with attaching-flangescl, a bolt and a spring (1 confined between an end wall of the casing and a in or stud d, projecting laterally from the b0 t. The near end of the bolt is normally flush with the near or front end of the casing, and the normally projecting head (i of the bolt serves to engage the retainer in a manner which will be resently described. The stud (1* Works in a ongitudinal slot (1 in the casing, and there is provided at the inner end of the slot d a lateral somewhat oblique slot (1 which terminates in a recess d. At the inner end of the slot d is a shallow recess d, with which the stud d is normally in engagement after the bolt enters the retainer under the action of its s ring. The bolt isretracted or turned at will y means of a key D, which has a flat'e'ntering portion (1 bearing a lateral' inclined projection d. I The bolt has its small end rovided with a longitudinal slot (1 from w 'ch branches an obll ue recess or perforation d, adapted to receive the proection d. To permit the key to be entered in either the normal position of the bolt or in the turned position of the same, the near end wall of the casing is provided with two slots (1 d, branching from the bore which re-' ceives the bolt. The slot d" and branch 0 ening d have opposite walls beveled some: @1813, as shown in Fig. 7, to permit the key to be rotated slightly after entry, whereby the key will be co ed by the bore, so that it will not slip when force to retract the bolt.

- movement of the sashes.

.2 5 opening movement the bolt is released and The manner of use will be readily under stood from the foregoing detailed description. When the Window is whollyclosed, the bolt enters the socket c", the head of the bolt hearing beneath the shoulder 0*. The head of the bolt is somewhat oval or elongated, and in the normal position of the bolt the long axis of the head of the bolt is vertical. Assuming the window to be Wholly closed and the bolt entered in the socket c, thekey may be entered and the bolt rotatedto bring the head beneath the shoulders at the struck in points c and at the same time in engagement with the inner surface of the flan es 0. When this rotation occurs, the stu :1 follows the slot d and draws the bolt outwardly slightl thereby binding the sashes together. the Window, the bolt is retracted b means of the key, (the key being first rotate slightly to the left after insertion,)which permits relative After the initial enters the enlarged opening c where'u on further movement causes the head of the olt ed with the flanges 0 flanking the s the retainer.

At any desired point the bolt may be ro-.

tated, causin the head to enterone of .the cavities c", t' ereby securing the sashes toether at any desired point, eft to the action of its spring, the relative movement of the sashes in opening the window will be limited by the en agement of the bolt with the 11 per end of t e slot 0, and it is noteworthy t at the bolt cannot be disenged from the upper fastener member or eeper except by practically-closing the window. The importance of t "s lies in the fact that it is impossible for a burglar to tam er with the fastener (even if supplied wit a bolt will 1 together to closer joint secured 11 6c key) as by reaching through above the upper sashor below the lower sash. Obviously the sashes may be thrown wide 0 en by withholding the bolt until the head t ereof passes above the opening 0, after which the bolt willride u on the outer surface of the retainer, bot in the opening and closing of the window finally enter the socket at the lower end of the retainer'and securely lock the sashes against openi andwhen the bolt is rotated in its socket ilac sashes will be drawn revent rattling and to make a between the sashes. v -Preferably the upper fastener member is sash, as s own, and the lower sash is prov1 with a vertical groove f to accommodate said member. It will be understood, however, that .an desired arrangement of the fastener mem rs upon-the window may be made. Minor changes in form and materials en it is desired to open If the 'bolt is and in the closing movement then the inner surface of the upper ed ssaem 1.
